Application filed March 26, 1912.

To all whom it may concern:

Be it known that I, LOUIS MARCONI, a

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Bottle-Closures, of which the following is a specification.

This invention relates to bottle closures, and particularly to means for making bottles non-refillable, and has for its object to provide a device of simple construction adapted to be manufactured at a low cost and assembled with a minimum of labor.

It is an object to provide an efficient form of valve the closing of which will at all times be secure with a simple form of casing therefor and a means for retaining the valve in operative position which will at the same time protect the device from being tampered with by the insertion of instruments, wire, or the like.

A further object is to provide such a device which will occupy a minimum amount of space.

Other objects and advantages will be apparent from the following description and from the drawings, in which- Figure 1 is an axial sectional view of a bottle neck equipped with my invention, Fig. :2 is a cross section on the line 22 of Fig. 1, Fig. 3 is a similar view on the line 3-3 of Fig. 1, Fig. 4 is a perspective of the retainer element.

There is illustrated a bottle neck 10, the outer portion of which is similar to the ordinary neck, the mouth 11 receiving a cork 12 wedged therein. The neck is slightly elongated, and is approximately cylindrical for the major portion of its length downward from the mouth, being slightly enlarged adjacent its base as at 12 and formed with a conical seat 13 smaller at its lower end than the cylindrical part of the neck. The neck is joined to the body 1-1 of a bottle at the base of this seat, in the ordinary shape, or any which may be desired for the purposes of the user. Engaged in the neck there is a closure mechanism A, including the lower casing element 15, substantially in the form of an inverted cap of elongated tubular form, which may be formed integrally.

The casing element 15 is slightly enlarged or rabbeted as at 16 at its upper end and provided with an outwardly extending terminal flange 17. Engaged beneath the Specification of Letters Patent.

flange and fitting the casing snugly there is a stopper 18 of cork, or other suitable material enlarged at its upper part, imme diately beneath which a plurality of openings 19 are formed through the casing to allow a proper flow of fluid therethrough, as will be described. The enlarged portion 16 is threaded on its inner side and engaged therein is the outer element 20, which comprises the threaded annulus 21, having the lateral flange its upper edge smaller than, and adapted to lie parallel with, the flange 17, the two flanges cooperating to retain the leather washer 23, which is fitted snugly therebetween. The washer 23 projects beyond the periphery of the flange 17 and fits into the enlargement 12, whereby the mechanism A is retained in the neck. It will be observed that the flange 22 is of less diameter than the space within the cylindrical part of the neck 10. The threaded portion of the annulus is of such thick ness that its inner surface lies flush with the inner surface of the casing 15, and is provided with inwardly projecting longitudinal lugs or ribs 2 adapted to serve as a check for the valve element 25, loosely reciprocable in the casing. The valve element is similar in form to the lower portion of the casing, and may be manufactured in the same way. It is provided with openings 19 adapted to register with those 19 in the casing when at the outer limit of its movement, where it is checked by the ribs 21. its length beneath the openings 19 is such as to allow those openings to fall into the lower closed portion of the casing 15, so that its upper part closes the opening 19when the device is in upright position.

Projected upwardly from the annulus 22 v and conforming in transverse contour to the ribs 21 and forming a continuation thereof, there are legs 2'? forming a cage supporting a protecting head 28 of cylindrical form, the body portion of which is of considerably less diameter than the passage through the neck and thus allows free passage of liquid therearound from the bottle. The transverse form of the legs and ribs mentioned is ii-shaped, the intersection of the sides being presented inwardly, whereby a minimum retardance of the flow of liquid occurs. The head is provided with a series of four, more or less, spaced laterally projecting helicoidal flanges 29 abutting snugly against the inner surface of the neck, but

allowing free movement of the device into engaged position, as will be described."

These flanges vary in their pitch slightly,

from the upper end-that is to say-they I are inclined downwardly to a greater degree at their upper end than at their lower. Their lower ends are also slightly recurved upward forming checks 30. These devices aim to prevent the introduction of wire beneath the head to engage and hold the valve, in open position.. Thus as viewed from the be practically impossible to withdraw the mechanism, as the washer is then engaged between the flange 17 and the shoulder in such a way as to become wedged tightly .when withdrawal is attempted. If desired,

,of course,v other means than the washer 23 may be utilized for the retention. of the mechanism A in the neck, such as a cement which may be incorporated in any suitable manner, or a resil ent metal collar 23 may be engaged between the casing 15 and the retainer, as'shown in Fig. 4, the collar being provided with tongues 28 adapted to snap beneath the shoulder 12 One method of using cement would be to fill the venlargement 12 with a' cement paste slightly beyond the adjacent surface of the cylindri ca-l portion 10 and extending down onto the conical seat a short distance. 23 would be entirely omitted, but the mechanism as otherwise described, would bein- The washer troduced, and the cork 18 after engaging the seat below the cement, will press upon the cement, causing it to move inwardly over the flange 17 after it passes the shoulder 12 and upon setting the mechanism will be held against removal. The retainer element is adapted to be cast integrally, though it may be formed in any manner found practicable, if desired.

It will be seen that the complete device is adapted to be produced at a low cost, and

tion with the interior of a bottle, :a packing material around the casing for snug engagement :upon said tapered part and wlth the flange below the shoulder, and a guard element constructed for fixed engagement with the upper end of the casing and having a flange thereon smaller than the first named flange, an annular retaining member between the flanges and extending into the said enlargement, the guard having a passage therethrough corresponding in size to that of the casing, also an extension below the last named flange engaged with the lowercasi'ng, and a gravity valve operable within the lower casing, and constructed to 'be checked in decanting position by the guard element. g
